Companies can create a chatbot that can interact automatically with (potential) clients. It's for example possible to book airline tickets via a chatbot, and countless other use cases come to mind: - schedule appointments - take surveys & quizzes - offer fitness programs - offer coaching - offer consultancy - offer shopping assistance - buy insurances - request permits - guide patients - etc. etc. etc.
In China, where most people don't own a computer but only a smartphone, chatbots are an important part of everyday life. Chinese can buy/arrange/request almost everything via bots, built on WeChat (their Facebook/WhatsApp). This trend is no spreading at high speed across the rest of the world!
